Abstract

NEW MATERIAL:An ester derivative of PS-5 of formula I.
EXAMPLE: Benzyl ester of PS-5 expressed by formula II.
USE: An antibacterial and an intermediate for their synthesis. Effective against Gram- positive and Gram-negative bacteria. Useful as additives for animal feed, bactericidal antiseptics for food preservation.
PROCESS: A compound of formula I or its ester-forming functional derivative, obtained by fermentation of PS-5 producing bacteria, e.g. Streptomyces SP-A 271 bacteria (FERM-P No.3984), is reacted with a compound of formula R-Z (R is 1W30C hydrocarbon group which may have a hetero atom; Z is halogen, OH, SH, etc.) in an inert solvent to give an ester derivative, e.g. the compound of formula III: (Y is O or S).
